Tim's mother was annoying

Like when she pitches a fit at Tim while in Tim's house about him not being open enough with her. Seriously she should be proud of him and the family he's built and the career he's established. In the same episode he tells Tim to "shut up" right in front of his kids in HIS HOUSE! What a rude guest.

Then she pitches a fit at Marty because he didn't have Christmas with his ex-wife. Yeah I'm sure the girls would really have enjoyed an incredibly awkward situation where their two divorced parents were attempting to pretend that everything was OK.

Tim's mother was just as annoying and self-righteous as Jill was. This show really didn't write women well.
